Leviticus 18:8

18:8 You must not have sexual intercourse with your father’s wife; she is your father’s nakedness.

Leviticus 18:12

18:12 You must not have sexual intercourse with your father’s sister; she is your father’s flesh.

Leviticus 18:11

18:11 You must not have sexual intercourse with the daughter of your father’s wife born of your father; she is your sister. You must not have intercourse with her.

tn Heb “the nakedness of your father she is.” See the note on v. 7 above. This law refers to another wife of the man’s father, who is not that man’s mother. The laws in the Pentateuch sometimes assume the possibility that a man may have more than one wife (cf., e.g., Deut 21:15-17).

tc A few medieval Hebrew mss, the LXX, Syriac, and Vulgate all read “because she is the flesh of your father,” like the MT of v. 13.

tn Heb “The nakedness of the daughter of your father’s wife born of your father, she is your sister; you must not uncover her nakedness.” That is, a half sister, the daughter of the man’s father by another wife, who is not the man’s mother, is to be considered a true sister. Therefore, the man must not have sexual intercourse with her.
